Through its impressive performance and adaptability, this Optolong L-eXtreme is the ideal choice for astroimagers seeking the precision needed for next-level narrowband images!
A High Performance Astrophotography Filter of the Utmost Quality
Let's Take a Deeper Look!
What sets one filter apart from another? Which filter is best for me? When developing a filter, manufacturers provide a chart that represents the wavelengths permitted through this filter. This gives insight into the filter’s performance, and what it can help you achieve. So, how exactly do I read a transmission chart? Our team has put together a comprehensive article, to help you understand the fundamentals on How to Read a Transmission Chart. Check out the article and feel more confident about choosing the right filter for your needs!
Stunning Detail on Emission Nebulae
This Optolong L-eXtreme is designed to be paired with colored cameras, collecting Ha and OIII wavelengths in one go. As opposed to utilizing multiple narrowband filters with a monochrome camera, this approach is much more efficient, allowing you to produce stunning narrowband images in a more timely manner. This filter shines when used on emission nebulae, such as the Orion Nebula, the Veil Nebula, the Elephant's Trunk Nebula, and plenty more, highlighting the various gasses present within these celestial bodies. Perfect for those in light polluted environments, the slim 7 nm bandwidth blocks out unwanted wavelengths, leaving behind detailed, high contrast images!
Compatible With Almost Any System
This filter is 2” in diameter and houses M48 x 0.75 threads, allowing it to effortlessly integrate into just about any setup! Whether you plan to utilize a filter drawer, a filter wheel, or a threaded connection directly to your telescope, this filter joins seamlessly. Also, the wide surface area fully covers full frame sensors, ensuring even illumination from corner to corner.
Engineered for Superior Performance
Crafted with B270 glass, this Optolong L-eXtreme is built with quality in mind, delivering exceptional transparency within the key wavelengths. Additionally, this filter houses multiple layers of anti-reflective coatings using Ion-assisted technology. This coating technology offers exceptional durability and scratch resistance, while simultaneously providing increased stability along the central wavelength (CWL). With a surface quality of 60/40, you can expect stunning, sharp images!
